Mfundo za Leveling Agents

Chidule cha Leveling ku

Pambuyo pogwiritsira ntchito zokutira, pali njira yowonongeka ndi kuyanika mufilimu, yomwe pang'onopang'ono imapanga chophimba chosalala, chofanana, ndi yunifolomu. Kuthekera kwa zokutira kuti zikwaniritse malo osalala komanso osalala kumatchedwa kuti kusanja katundu.

M'malo opangira zokutira, zolakwika zomwe zimachitika nthawi zambiri monga peel lalanje, maso a nsomba, ma pinholes, shrinkage cavities, retraction m'mphepete, kumva kutuluka kwa mpweya, komanso zizindikiro za burashi panthawi yotsuka ndi ma roller marks. pakugwiritsa ntchito roller-zonse chifukwa cha kusakwanira bwino-onse pamodzi akutchedwa kusalinganika kosakwanira . Zochitika izi zimawononga ntchito zokongoletsa ndi zoteteza za zokutira.

Zinthu zambiri zimakhudza kuyanika kwa kuyanika, kuphatikiza kusungunuka kwamadzimadzi ndi kusungunuka kwa zosungunulira, kugwedezeka kwa nsanjika, makulidwe a filimu yonyowa ndi kugwedezeka kwapamtunda, mawonekedwe a rheological of zokutira.,njira zogwiritsira ntchito, ndi zochitika zachilengedwe. Zina mwa izi, zomwe zimakhala zovuta kwambiri ndi kugwedezeka kwa pamwamba pa zokutira, kugwedezeka kwapamwamba komwe kumapangidwira mufilimu yonyowa popanga filimu, ndikukuthekera kwa filimu yonyowa kuti ifanane ndi zovuta zapamtunda.

Kuwongolera kuyanika kwa zokutira kumafuna kusintha kapangidwe kake ndikuphatikiza zowonjezera zowonjezera kuti zitheke kulimba koyenera komanso kuchepetsa kugwedezeka kwapamtunda.

Ntchito ya Leveling Agents

Wothandizira kusanjan ndi chowonjezera chomwe chimayang'anira kayendedwe ka zokutira pambuyo ponyowetsa gawo lapansi, ndikulitsogolera kuti lifike kumapeto kosalala, komaliza. Leveling agents amathetsa mavuto awa:

Pamwamba Kuthamanga Gradient-Air Interface

Chisokonezo chomwe chimayamba chifukwa cha kugwedezeka kwapamwamba pakati pa zigawo zamkati ndi zakunjakuKuchotsa ma gradients apansi panthaka ndikofunikira kuti pakhale malo osalala

Pamwamba Kuthamanga Gradient-Chiyankhulo cha Substrate

Kuthamanga kwapansi kwapansi kuposa gawo lapansi kumapangitsa kunyowetsa kwa gawo lapansi

Kuchepetsa zokutira's kuthamanga pamwamba kumachepetsa kukopa kwa intermolecular pamtunda, kulimbikitsa kuyenda bwino

Zinthu Zomwe Zimakhudza Kuthamanga Kwambiri

Kukhuthala kwakukulu→kuwongolera pang'onopang'ono

Mafilimu okhuthala→mofulumira kusalaza

Kuthamanga kwapamwamba pamwamba→mofulumira kusalaza
